January 24, 2021 updated by: Murat Yassa, Bartin State Hospital

Sleep Patterns and Disturbances in the Second and Third Trimester of Uncomplicated Pregnancy

Sleep disorders and disturbances are mostly underestimated in clinical practice. Moreover, this problem is generally neglected by the pregnant themselves. Today, it is important to underline any problem that may have an affect to improve the quality of life during pregnancy.

This study assesses the sleep quality, insomnia patterns and obstructive sleep apnea in the second and third trimesters of pregnancy.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Pittsburgh Sleep Quality Index (PSQI)
Time Frame: Through study completion, an average of 39 weeks
The order of the PSQI items has been modified from the original order in order to fit the first 9 items (which are the only items that contribute to the total score) on a single page. Item 10, which is the second page of the scale, does not contribute to the PSQI score. In scoring the PSQI, seven component scores are derived, each scored 0 (no difficulty) to 3 (severe difficulty). The component scores are summed to produce a global score (range 0 to 21). Higher scores indicate worse sleep quality.
Through study completion, an average of 39 weeks
Berlin Questionnaire
Time Frame: Through study completion, an average of 39 weeks
The questionnaire consists of 3 categories related to the risk of having sleep apnea. Patients can be classified into High Risk or Low Risk based on their responses to the individual items and their overall scores in the symptom categories. High Risk: if there are 2 or more categories where the score is positive. Low Risk: if there is only 1 or no categories where the score is positive.
Through study completion, an average of 39 weeks
Stop-Bang questionnaire
Time Frame: Through study completion, an average of 39 weeks
This questionnaire evaluates the risk of sleep apnea. Low risk of OSA: Yes to 0-2 questions Intermediate risk of OSA: Yes to 3-4 questions High risk of OSA: Yes to 5-8 questions or Yes to 2 or more of 4 STOP questions + male gender or Yes to 2 or more of 4 STOP questions + BMI > 35 kg/m2 or Yes to 2 or more of 4 STOP questions + neck circumference.
Through study completion, an average of 39 weeks
Insomnia Severity Index (ISI)
Time Frame: Through study completion, an average of 39 weeks
ISI measures the insomnia and related parameters. Scoring and Interpretation as follows: Add the scores for all seven items (questions 1 + 2 + 3 + 4 + 5 +6 + 7) will give the total score. Total score categories: 0-7 = No clinically significant insomnia 8-14 = Subthreshold insomnia 15-21 = Clinical insomnia (moderate severity) 22-28 = Clinical insomnia (severe)
Through study completion, an average of 39 weeks
